When the primary winding of the transformer is connected to an alternating current network, a voltage of 30 V appears in the secondary winding. When the secondary winding is connected to the same network, a voltage of 120 V appears at the terminals of the primary. How many times is the number of turns of the primary winding of the transformer greater than the number of turns of the secondary winding?
